WALDEN EDDY, OF GREENWICH, NEV YORK.

SHOVEL-PLCW.

SPECIFICATION forming part" of Letters Patent No. 289,238,1:lated November 27, 1883.

Application filed April 18, 1883. (No model.)

the plow, for loosening the ground laterally beyond the center of the rowin which the shovel-plow works, and nearer to the growing crop.

The invention mainly consists in a novel combination,with the point, wings, and moldboard of' the plow, which is preferably made with a cast beam and standard, of' the subsoil attachments or teeth, and means for securing and adjusting the same, and every facility is afforded for adjusting said teeth to w ork closer or farther apart, and shallower or deeper, also for their detachment when not needed.`

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure l represents a view in perspective of a plow'embodying my invention; .,Fig. 2, an inverted plan, upon a larger scale,of said plow in part. Fig. 3 is a face view of the forward portion of one of the subsoiling attachments.

A A in the drawings indicate. the beam and standard of the plow, made of castmetal in one piece. Bis the shovel-point, Cthe mold-board, and

-D D the wings7 of the plow.

E E are the handles.

G G are the subsoil attachments or spring-` teeth, arranged to project from opposite sides of the winged shovel-plow, and so as to work at a lower depth than the point of it, for the purposes hereinbefore mentioned. These teeth or attachments G G are formed of iiat bars bent and arranged to project laterally and backwardly in diverging directions from the under side ofthe mold-board C, and are curved downwardly, and suitably twisted or bent at their rear ends, as at b, to bring their points in proper subsoiling position. The forwardV portions of these attachments G G, which rest on or against the under side of themold-board C, are each made with elongated slots d d in 5 5 them, the one in rear of the other. These slots should be suitably shaped to provide for every necessary adjustment of the subsoiling attachments*that is, to provide for said at` tachment being widened or contracted, and to run deeper or shallower at. their points. For these purposes tue rear slot, d, may be made of T shape, and the forward one, d', be of an obtuse angular construction, as shown in Figs. 2 and 3. The bolts e e, which pass through said slots to secure the adjustable attachments G G, are the samebolts as are used to hold the point B and wings D D to the mold-board C, and pass not only through the mold-board and shovel-point and wings, but also through the slotted portions of the subsoiling attachments. In this way the construction is simplified, as thesame sets of bolts answer a double purpose, and both the mold boards and wings are strengthened by the subsoiling attachments G 7 5 G passing under them. By slackening the bolts c e said subsoiling attachments may readily be adjusted as required, and the bolts afterward be tightened up again or they may be easily removed from the plow when not needed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y 1. rIlhe combination, with the point Bof the shovel-plow, its wings D D, and mold-board C, of the adjustable subsoiling attachments or teeth G G, and the bolts e e, arranged to pass through slots in said attachments and through the point, wings, and moldboard of the plow, substantially as specified.

2. The subsoiling attachments or teeth G G, of flattened bar construction, bent to diverge backwardly from under the mold-board of the plow, and curved downwardly and forwardly at their rear ends, also provided with slots d d at or in their forward portions, in combination with the mold-board C, the cast beam and standard A A', the shovel-point B, the wings D D, and the bolts e e, essentially as roo shown and described.
